We propose a multi-swarm approach to approximate the Pareto front of general multi-objective optimization problems that is based on the consensus-based optimization method (CBO). The algorithm is motivated step by step beginning with a simple extension of CBO based on fixed scalarization...

We present a branch-and-bound method for multiobjective mixed-integer convex quadratic programs that computes a superset of efficient integer assignments and a coverage of the nondominated set. The method relies on outer approximations of the upper image set of continuous relaxations. These...

Home Health Care (HHC) services are essential for delivering healthcare programs to patients in their homes, with the goal of reducing hospitalization rates and improving patients' quality of life. However, HHC organizations face significant challenges in scheduling and routing caregivers for...

Every investor has some difficulties when investing into crowdfunding campaigns, as it is not clear how to evaluate specific crowdfunding campaign or what success factors to choose. The aim of this study is to propose the crowdfunding campaign assessment model, test it empirically and illustrate...
